About coding Word developmental blindness
The ICD-10-CM code for Word developmental blindness is F81.0 (Specific reading disorder). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F81.0.
Within F81 (specific developmental disorders of scholastic skills), F81.0 is specifically for specific reading disorder. Related codes cover Mathematics disorder (F81.2), other developmental disorders of scholastic skills (F81.8) and developmental disorder of scholastic skills, unspecified (F81.9).
Don't report F81.0 together with the conditions in its Excludes1 note: alexia NOS (R48.0) and dyslexia NOS (R48.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
